摘要:
A pipe insulation system includes a tubular core of fibrous insulation and a flexible closed cell foam layer overlaying the core and forming an outer surface of the system. The tubular core has a first longitudinal slit extending completely through the wall of the core and a second longitudinal slit in the inner surface of the tubular core, opposite the first slit, that forms a hinge permitting the tubular core to be opened and closed to place the system about a pipe. Preferably, the foam layer has a water vapor permeance rating of 0.02 perms or less and the pipe insulation system includes a seal for sealing the first slit so that an outer surface layer of the sealed system formed by the foam layer and seal has a water vapor permeance rating of 0.02 perms or less.

Embodiments of the invention provide systems, devices, and methods for mounting a photovoltaic module to a structure, such as a roof. An embodiment of a method for mounting a photovoltaic module to a structure may include providing a photovoltaic module, a first mounting device, and a second mounting device. The first mounting device and the second mounting device may be coupled with the structure, such as a roofing membrane, so that opposing mounting channels of the respective devices face one another. The method may further include inserting a first edge of the photovoltaic module within the mounting channel of the first mounting device and inserting a second edge of the photovoltaic module within the mounting channel of the second mounting device so that the photovoltaic module is disposed between the first mounting device and the second mounting device.

A method of predicting and communicating transient hygrothermal behavior of an installed building component in a building wherein an interior environment of the building is materially affected by an environment exterior of the building, includes: defining a performance characteristic of the building component that is affected by transient hygrothermal behavior of the building component; defining exterior and interior climatic factors that affect the defined performance characteristic wherein the interior climatic factors are a function of the exterior climatic factors; and defining one or more non-climatic factors that affect the defined performance characteristic. Inputting these factors into a transient hygrothermal simulation software program to create a software model for performing simulations which predict changes in the defined performance characteristic, as a function of time, that are compared with a threshold performance characteristic value, to provide a user guide.

Embodiments of the invention provide systems and methods for mounting a solar panel to a roof of a building or structure. Structures used to mount a solar panel to a roof may include a base having a flange that extends partially or fully around a periphery of the mounting unit, a mounting surface connected with the base and configured to couple with the solar panel so that the solar panel is elevated above the roof's surface and/or oriented at an angle with respect thereto, and one or more walls or members that connect the mounting surface to the base. A flexible membrane or skirt may be coupled with the flange and may extend laterally therefrom. The flexible membrane or skirt may be coupled with the roof to secure the mounting unit and solar panel to the roof.

An acoustic ceiling panel for a lay-in or suspended ceiling includes a core portion, and front and rear layers covering front and rear sides, respectively, of the core portion. The air flow resistance of the core portion does not exceed about 100 MKS rayls. The air flow resistance of the front layer lies in the range of about 300 to about 800 MKS rayls. The air flow resistance of the rear layer lies in the range of about 300 to about 1200 MKS rayls. The panel would be supported on a grid suspended below a structural ceiling to form an air space therebetween.
